Each glucose molecule consists only of carbon, hydrogen, and oxygen atoms. If each molecule contains 53.3% oxygen and 6.7% hydrogen by mass, what percentage of each glucose molecule is made up of carbon?

Question

ollieboyne · Answer

Percentage = 100 - 53.3% - 6.7% Percentage = 40%

ollieboyne · Answer

The percentage of carbon in each glucose molecule is 40%. This is calculated by subtracting the percentages of oxygen and hydrogen from 100%. Thus, glucose is composed of 40% carbon by mass.
